Our current I2C setup works with the NOTE-WIFI (v1.2) but we are unable to communicate to the NOTE-ESP (v2.1). We updated the note-c library to the latest, but still no luck. We tried numerous NOTE-ESP cards as well as the developer and release firmwares. We ruled out any hardware issues (i.e. verified using NOTE-WIFI, checked I2C and data signals, etc).
Any ideas?
Thanks!
Hi @WhiteShoes and welcome to the Blues community!
You have me a bit stumped on this one, as there shouldn’t be any differences between NOTE-ESP and NOTE-WIFI that could cause this. Which Notecarrier are you using (or is this a custom design)? Are you seeing any LED activity on NOTE-ESP when you power it on?
Thanks,
Rob
Hey, thanks for the quick reply. This is a custom design. On initial power up the red LED blinks quickly (gradually gets faster) and then stops. This is followed by three flashes (about 3 seconds long each) and then no other flashing.
